Wing-Body-No Tail: DPW4_wb_no_tail_v03.igs.gz

Wing-Body-Tail, i_H = 0 : DPW4_wbt_ih+0_v03.igs.gz

Wing-Body-Tail, i_H = +2 : DPW4_wbt_ih+2_v03.igs.gz

Notes on IGES geometry files:

These files have been compressed with gzip.
CADFIX: The current release of CADFIX does not show the center section of the fuselage above the wing.
Gridtool: By default, Gridtool only turns on trimmed surfaces. The center section of the fuselage above the wing is not trimmed and does not show by default. To show this section, go to the surface panel, select all (instead of single), select "off" and select "wireframe".
